Cleveland Browns quarterback Johnny Manziel wouldn’t be the first NFL rookie to learn that to make it as a professional, it takes a little more effort than you’re used to. Manziel isn’t the typical rookie in that he has already become the NFL’s next villain to many folks, but he’s going through the normal growing pains. He struggled in his first start. In his second start, on Sunday at the Carolina Panthers, he wasn’t off to a great start before he was knocked out of the game with a hamstring injury . According to The Cleveland Plain Dealer’s story from the game , Manziel seems to realize that even though he was an all-time great college player, it’s going to take more dedication to replicate that success in the NFL. A taste of starting has seemingly motivated him, and the struggles have too. “And that’s what I want to do and that’s what I want to be for this organization so for me, if anything, this has motivated me more to head into this offseason,” Manziel said, according to the Plain Dealer. “We had a better team than we have had here in years past, and we need to capitalize on these guys that we have coming back next year and the talent that we do have on this roster that our coaching staff and our management has put on this team.” Manziel doesn’t have the absolute support of the Browns going into 2015. After Manziel’s first start, coach Mike Pettine said , “ He could hit it out of the park the next two and there’ll still be doubts. He could not play very well the next two, there’d be a ton of doubts.” If
